Question

Freelance

Greetings
Once upon a time I came across a service for calling strangers. Now I'm trying to find it and can't find it.
The essence of the service, according to memoirs, was as follows: you register, choose a participant with a task and, for example, call him at the appointed time and say something.

Answer 1

there was such a thing - a Buddhist, you register, you make an application (like I want to wake someone up), the person who wants to be awakened also leaves an application, the service connects you - and you chat with a stranger (sorry for explaining clumsily), maybe it?

Answer 2

It's called a prank.

Answer 3

In general, I have noticed such a service on the Internet more than once - a call-centre for calling cold customers, there, according to a sales script, they are always ready to sell something to someone) did you mean that?
